// In order to disable the native drag preview you can
// use `event.dataTransfer.setDragImage()` to set a small
// invisible image as the drag preview.
// There are alternative techniques,
// (eg setting opacity to in onGenerateDragPreview and then 1 in onDragStart)
// but the technique in this file worked best across browsers and platforms

// Here we are preloading the image so that it is ready for the first drag.
// Even though the image is base64 encoded, the browser queues an async task
// to decode the image. The image needs to be decoded before it can be used
